Yocto自定义图像配方未将文件安装到最终的rootfs中

Question

我写了以下自定义的Yocto Bitbake食谱。 我将执行某些ROOTFS_POSTPROCESS_COMMAND，如下所示，作为包含此配方的完整映像构建的一部分。 当前，该映像在映像do_rootfs步骤中，因为rootfs目录中缺少TIInit_11.8.32-115200_no_dsm-TI_P2.136.bts文件。

cleanup_ble_baud_rate_function() {
    mv ${IMAGE_ROOTFS}/lib/firmware/ti-connectivity/TIInit_11.8.32-115200_no_dsm-TI_P2.136.bts ${IMAGE_ROOTFS}/lib/firmware/ti-connectivity/TIInit_11.8.32.bts
}

ROOTFS_POSTPROCESS_COMMAND_append_am57xx-phycore-rdk_arago = " cleanup_ble_baud_rate_function;"

这是食谱：

do_install() {
  install -d ${D}${bindir}
  install -m 755 ble-service.py ${D}${bindir}
  install -m 755 setup-bluetooth-radio.sh ${D}${bindir}

  install -d ${D}/lib/firmware/ti-connectivity
  install -m 755 TIInit_11.8.32-115200_no_dsm-TI_P2.136.bts ${D}/lib/firmware/ti-connectivity/

  install -d ${D}${sysconfdir}/systemd/system/multi-user.target.wants
  install -m 0644 ${S}/bluetooth.service ${D}${sysconfdir}/systemd/system
  ln -s ../bluetooth.service ${D}${sysconfdir}/systemd/system/multi-user.target.wants/bluetooth.service

  # Actually use socket based activation for this service
  install -d ${D}${sysconfdir}/systemd/system/sysinit.target.wants
  ln -s ../bluetooth.service ${D}${sysconfdir}/systemd/system/sysinit.target.wants/bluetooth.service
}

映像构建失败后，当我执行Linux Updatedb和locate命令时，将显示以下结果：

我同意Oleksandr的观点。 不要使用postprocess命令，它可能没有按照您的想法做。 相反，只需确保使用$ {S}，并且FILES _ $ {PN}可能会简单得多。

install -m 755 ${S}/TIInit_11.8.32-115200_no_dsm-TI_P2.136.bts ${D}/lib/firmware/ti-connectivity/

FILES_${PN} += "${libdir}/firmware/ti-connectivity/*"

在tmp / work / target / recipename中调试配方安装将帮助您弄清楚事情的发展方向。
